Quantum Bias Cosmology: Acceleration from Holographic Information Capacity
Luke M. Butcher
I show that a generic quantum phenomenon can drive cosmic acceleration without the need for dark energy or modified gravity. When treating the universe as a quantum system, one typ…
Path integrals with discarded degrees of freedom
Luke M. Butcher
Whenever variables are discarded from a system, and the discarded information capacity depends on the value of an observable , a quantum co…
Quantum effective potential from discarded degrees of freedom
Luke M. Butcher
I obtain the quantum correction that appears in the effective potential whenever a comp…
Lambda does not Lens: Deflection of Light in the Schwarzschild-de Sitter Spacetime
Luke M. Butcher
Debate persists as to whether the cosmological constant can directly modify the power of a gravitational lens. With the aim of reestablishing a consensus on this issue, I condu…
Traversable Wormholes and Classical Scalar Fields
Luke M. Butcher
I prove that general relativity admits no asymptotically well-behaved static spherically symmetric traversable wormholes supported by classical scalar fields and nonexotic matter.…
Casimir Energy of a Long Wormhole Throat
Luke M. Butcher
We calculate the Casimir energy-momentum tensor induced in a scalar field by a macroscopic ultrastatic spherically-symmetric long-throated traversable wormhole, and examine whether…
